Action Plus vs ......... any gains?

the tuning your talk'n about may get me into the 13's. Perhaps. There may be something left in the tune, but I'm a tweaker :D I believe it's at 16* initial, and 36* full. I've tried adding and pulling out, but this is where it ran the best. Probably some jetting games to be played with the carb.
  • My 318 Duster is at 20* and 40*, that's where it ran the best. My rule is I ALWAYS let the car decide where it wants to be timed. I never say 20* and 35* and walk away.

Yeah cause it picked up with the bigger carburetor.....might be more in it with making it more rich. It might want more. In a race situation, they usually do.
